What should I know about safety edge and photocell repairs in Welling?

Photocells can often be added to doors that only have a safety edge, if the control box allows it.
The engineer tests the whole circuit, because a damaged cable or control box fault can look like a failed device.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.
Never tape over, bridge or bypass a safety device to make an electric roller door close.

How does it work in Welling?

The engineer tests the circuit and replaces the faulty device, then tests the door. Any further parts are quoted before they're fitted.

Rules that apply in Welling

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

Electrics

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.

Safety edge and photocell repairs in Welling: questions

What should I do while I wait for a visit in Welling?

If the door is stuck part-open, keep people, pets and cars clear of it and switch off the power at the isolator if it is safe to reach. Do not force the curtain or open the roller box. Your Welling visit date is confirmed in writing.

Can I get a price for Welling without anyone visiting?

Yes. The guide price tool takes four steps and gives a range for your opening and door type. It is a guide, not a quote: the written quote comes after the survey or once the visit price is agreed.

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.

Do you cover Welling?

Yes. Welling is part of the area we cover in Greater London, including DA16, DA6 and DA15. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

Do you repair safety devices on any make of roller door?

Yes. We repair and replace safety edges and photocells on electric roller garage doors of any make, provided compatible parts are available for the control box. We don't work on sectional or up-and-over doors. If a compatible part isn't available, we'll explain the options before anything is booked.

Can I bypass the photocells to get the door shut?

No. Bypassing, bridging or taping over a safety device removes the protection that stops the door closing onto a person, pet or car. If the door won't close, switch it off at the isolator, keep the area clear and request a visit. Tell us if you're concerned about security when you get in touch.
